@manu Yes, I don't mean annotations. When opening a pdf with a form, it shows a message with a button that lets you toogle between seeing input forms on top of every form field or seeing the input text as normal text inside the pdf.

To be fair the fact that waving works directly instead of having to go to save as is pretty new.

I think the file I was given does not have proper built-in forms, it's just a PDF.

When it's just one page, I open it in Inkscape and I can do whatever I need. This is multi-page and I'm kind of surprised there isn't a simple "write on a layer above" kind of option. I wonder how others users do this.

Anyway, I think that this, and many other GNU-bugs, has made me really think, so I'm not going to fill out this PDF yet.: ]
